Siren Alarm !

I have had it happen to me 3 or 4 times now....

once I was installing linux and the others i was playing world of warcraft and battlefield 2.....


All of a sudden its like a temp warning siren goes off

my temps are good my cpu is at like 45c or so on load

im at 3.8ghz with 1.53v on core.

After this last time I added a 80mm delta fan over the sinks and ram and a 40mm sunon as well...

I hope this fixed my problem....

any suggestions to what it might be?

What was the pattern of the alarm?

ON off ON off ON off

repeatedly

my system would still work fine

After I would reboot It would go away

The alarm will sound for high temp or voltage too low/high or low fan RPM.
